Maxum 4100 scb shaft seal
 

I'm trying to find part number or size of shaft seal for Maxum 4100 scb.
anybody has this info to share please?
as well as propellers part number?

I think the part only depends on the shaft diameter. You will need to pull the shaft out some in order to change the part.

I did take the measurements of shaft and found 2" dia.and stern tube is 3.5" and got it imported from US via supplier.
Thanks

Is the seal leaking? I had problems way back. The collar adjusted to the carbon sleeve where water enters for cooling. If the water pressure from the engine is high it will cause the seal to pulse when the engine is running. Just put a valve to throttle the flow and pressure. Had everything replaced when the boat was brand new. It leaked and this is what we found was the solution. This boat has diesel engines.

Hi Dennis,
yes seal was leaking and i got new seals few weeks back,hopefully will finish repairs in dock and try new ones in water.

The stainless steel collar can be adjusted for compression to the carbol cooling block.
My dripples packing is the orginal on port engine and I had to adjust it three times. From your pictures I doubt you needed to nerw seals.

The collar has two set screws one behind the other.

i was trying to stop water leakage from carbon piece ,then while removing the water hose the carbon piece broken.
